IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 19,321, dated February 9, 1858; Additional Improvement dated August 2, 1859; Reissue No. 3,071, dated August 4, 1868.

To all whom it may concern:

.me it known that I, GEORGE \VATT, of Richmond, in the county of Heurico and State needless to make it a mattter of detailed exof Virginia, have invented certain new and useful Improvements in Flows; and 1 do hereby declare that the following is a full, i

clear, and exact description of the constructiou and operation of the same, reference being had to the annexed drawings, forming.

part of this specification, on Sheet 1 of which drawings- Figure l is a mold-board elevation of my improved plow. Fig. 2 is a land-side elevation. Fig. 3 is a front view, showing the curve the beam and the eccentric roller.

Similar letters of reference indicate the same parts in the different figures.

One importantfeature of this invention consists in so constructing the plow that while the landside shall have an inward inclination from its base the neck orstandardabove the landside shall have an outward inclination, so that in operation the oblique landside serves to hold or properly confine the plow in the ground, leave an overhanging side to the furrow to facilitate the turning of the succeeding furrow, and, when cultivating, to loosen up the surface-ground about the roots of the plants, while the outward projecting neck or standard serves to press or throw the earth toward the growing plants on the unplowed ground or land.

It will be seen that in carrying out this part of the invention it is not necessary to adopt the particular construction represented in the drawings and described .in' the ensuing specification. Thus it is manifestly immaterial to the point in question whether the inwardlyinclining landside and outwardly-inclining breast or standard have curved surfaces, as represented, or straight surfaces. As apractical representation of this feature is given in the drawings and a suflicient description embodied in the following specification, it is Fig. 3 is a section on line yy, showing the notches on planation.

The invention further consists in constructing both mold-board and landside of cylindrical surfaces, the turn of the mold-board commencing from the extreme point, and the cutting edge being determined by the intersection of the said cylindrical surfaces, the mold-board having its concavity outward and the landside its convexity outward, said construction being combined with the curved standard, hereinafter to be described.

The invention further consists of a novel cuff attachment, hereinafter described, the

same forming the subject of the additional improvement above referred to..

In the drawings, M is the mold-board; L, the landside; S, the standard, and B the beam. The mold-board turns outward in a regular cylindrical surface from its intersection with the share, the elements of the cylinder being respectively parallel to this line of intersection.

. The landside L is a regular cylindrical surface of the same diameter as the cylinderot' which the mold-board forms a portion, the front or cutting edge of theplow being formed by the intersection of their two surfaces.

The standard S curves landward from the upper extremity of the cylindrical landside, being cut away and hollowed out on the moldboard side to prevent clogging, as described in my patent of December 9, 1856, reissued November 10, 1857.

The landside L, being of cylindrical form, passes obliquely under the soil, by which the plow is rendered much more steady, as it is prevented from rising at the heel or tilting shown in the drawings, permits the rising, v

earth to pass off without clogging. under the beam, and its landward inclination causes it to push the loose earth toward plants on the unplowed ground.

I do not claim of itselfthe inclination of the landside toward the mold-board for the purpose of leaving soil overhanging the furrow, as such device, broadly considered, is not new.

0n the lower branch of the cult attachment, (sec Sheet 2,) for forcing the beam against the upper branch thereof, is an eccentric roller, whereby the lateral pressure of the cuft'on the beam may be diminished. The rear of the beam is secured to the handles by a single bolt, and the handles to their attachments each by a single bolt, so thatthe depth of plowing is graduated by adjusting the beam in the cuff. There are notches on the top of the beam for the reception of the upper branch of the cuff, or a notched plate placed thereon. In the drawings, H is the handles; 13, the beam; M, the rnold-board5 L, the landside, which are secured to each other by the lap ping flanges aand a, b and b, bolted together. 0 is the brace, extending from mold-board the growing to landside, having flanges d, to which the mold-board and landside are bolted, and also two arms, 0 e, to which the handles are secured by a single bolt. 1 S is the standard, to which is fastened the cuff f, through which the beam passes, having on its lower branch an eccentric roller, 1', for 1 forcing the beam against the upper branch thereof, thereby diminishing the lateral pressure of the cuff on the beam, and the rear of the beam being secured to the handles by the single bolt h, and the handles to their lower attachment, 0 e, by single bolts, the beam can be adjusted in the cuff f, there being notches i i in the top of it to receive the upper branch of the cuff, and thus regulate the depth of plowing.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:

1. The combination,in a plow, ofa landsidc having an inward inclination from its base toward the mold-board, and a neck, breast, or standard having a diverse or outward inclination, substantially as setforth.

2. Constructing mold-board and landside of cylindrical surfaces intersecting along the cutting edge of the plow, in combination with the curved standard S, the Whole being constructed substantially as and for the purposes hereinbefore set forth.

.3. The combination of the eccentric roller 1", beam B, notches i, and cuft'f, substantially as set forth.
